VEHICLE-SPINDLE.

Application filed April 7, 1914.

To all whom it may concern Be it known that I, WVALTER L. BLACK, acitizen of the United States, residing at Allen, in the county of Dixonand State of Nebraska, have invented certain new and useful Improvementsin Vehicle-Spindles; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to vehicle spindles and more particularly to theautomatic lubricating type of spindles, and has for one of its objectsthe provision of means for supplying the lubricant to the spindle orskein at the points of greatest wear.

A further object of this invention is the provision of means forindependently lubrieating the end of the spindle or skein, wherebyeither or both of the ends at the points of greatest wear may belubricated as desired.

A still further object of this invention resides in the construction ofa thimble skein or spindle which may be readily applied to any of thewell known axle constructions now in use with but a slight change in theaxle construction. And a still further object of this invention residesin the construction of an automatic lubricating skein or spindle forvehicles, which is simple in construction, efficient and durable inpurpose and which can be manufactured at a nominal cost.

These and other objects will more fully appear and the nature of theinvention more clearly understood by the construction, combination andarrangements of the parts thereof, as described in the followingspecification, defined in the appended claims and illustrated in theaccompanying drawings, in which,

Figure 1 is a vertical longitudinal sectional view of my inventionshowing the construction of the assembled parts and the manner in whichthe same is applied to the usual axle of a vehicle. Fig. 2 is a verticaltransverse sectional view taken on line 22 of Fig. 1 looking in thedirection of the arrows, showing the manner in which the lubricatingpipes of the skein are seated in the groove formed within the axle, and,Fig. 3 is a fragmentary sectional detailed view of one of the restrictednozzles of one of the Specification of Letters Yatent.

lubricating pipes showing the manner in which the nozzle is crimpedwithln the recess formed in the upper part of the skein.

I deem it advisable to here state that for the sake of convenience andillustration, I have here shown my invention as applied to the thimbleskein of a wagon, but it is to be clearly understood that I do notrestrict my invention to this particular use, as the same is equallyadapted for use in connection with buggy or other vehicle spindles ofthe iron axle type, the only difference being, in the latter case, thatin place of the groove formed in the wooden axle of a wagon, the spindleof the iron axle may be formed with a bore in place of the groove.

Referring to the drawings 1 denotes the axle having formed in the uppersurface thereof the elongated groove or channel 2, which groove orchannel 2 may be formed upon the top of the axle, the bottom or ateither side as preferred and arranged upon the axle 1 and embracing thechannel way 2 is a thimble skein 3 retained upon the axle 1 through themedium of the screw bolt 1, the head 5 of which is seated in the recess6 formed in the outer end of the skein 3, the skein 3 being alsoprovided with the nut or tap 7 for retaining the wheel upon the skein.The skein 3 has formed at the inner upper portion thereof the coverplate 8, the skein 3 with its cover plate 8 entirely inclosing thegroove or channel 2 of the axle 1, the cover plate 8 being provided withthe aperture 9 through which projects the upwardly curved portion 10 ofthe lubricating pipe 11, and upon the projecting end 10 is arranged thelubricating cup 12 for holding any suitable lubricant being preferablyhard oil. The pipe 11 is designed to lie within the groove or channel 2of the axle 1 at one side thereof and has arranged upon its outer endthe upwardly extending restricted nozzle 18 projecting upwardly throughthe converging aperture 14: terminating in the recess 15 formed in theskein 3, the protruding end of the restricted nozzle 13 being crimped asshown at 16 within the recess 15, the upper edge of the crimped portion16 lying 1n a plane below the outer surface of the ske1n 3 thus formingan auxiliary reservolr adjacent the outer end of the skein 3 forsupplying the lubricant thereto. The function of the restricted nozzleis to control the flow of the lubricant in the pipes and too rapid flowthrough the pipes.

Arranged within the cover plate 8 of the skein 3 slightly to one sideand rearwardly of the aperture 9 is the aperture 17 through whichprojects the up-turned portion 18 of the lubricating pipe 19, and uponthe protruding end of the portion 18 is arranged the lubricating cup 20similar in construction to the lubricating cup 12 of the pipe 11. Thepipe 19 being seated within the groove or channel 2 of the axle 1 at oneside thereof and lying in the same plane and in close contact with thepipe 11, the pipe 19, however, being of shorter length than the pipe 11,and being provided at its outer end with the upturned restricted nozzle21 projecting through the converging aperture 22 terminating in therecess 23 formed in the skein 3 adjacent the shoulder 25 thereof, theprotruding end of the nozzle 21 of the pipe 19 being also crimped as at24, the upper surface of the crimping portion 24: lying in a plane belowthe upper surface of the skein 3, thus providing an auxiliary reservoiradjacent the shoulder portion 25 of the skein 3.

It is to be here noted that I have provided an automatic lubricatingskein or spindle for vehicles, wherein thelubricant may be supplied tothe portion adjacent the end of the skein or spindle, or to the portionadjacent the shoulder 25 thereof independently of each other, if sodesired, or the lubricant may be simultaneously supplied to both ends ofthe skein or spindle if desired. The lubricating cups 12 and 20 are tobe supplied with any suitable lubricant, preferably hard oil, thelubricant being conveyed by the respective pipes 11 and 19 to thenozzles 13 and 21, the lubricant from the nozzles 13 and 21 fill theauxiliary reservoirs 15 and 23 respectively to a point of a slightoverflow, but at the same time there remains in the reservoirs 15 and 23sufficient lubricant to prevent a constantly supply these points ofgreatest A Wear with the hard oil or other fluid.

I have here shown and described the preferred embodiment of myinvention, but I hereby reserve the right to make such variations andalterations therein from time to time as I may deem expedient and whichwill not depart from the spirit of the invention nor conflict with thescope of the claims.

Having thus fully described my invention what I claim as new, and desireto secure by Letters Patent of the United States is 1. A lubricatingspindle for vehicles, in combination with an axle, a spindle thereon,said axle and said spindle having cooperating channels, pipes withinsaid channels for independently conveying a lubricant to each of therespective ends of said spindle, one of said pipes being of less lengththan the other of said pipes, a lubricating cup for each of the saidpipes and a restricted nozzle on the end of each of said pipes, wherebythe flow of the lubricant is retarded and controlled in the said pipes.

2. A lubricating spindle for vehicles, in combination with an axle, aspindle'thereon, said axle and said spindle having cooperating channels,pipes within said channels for independently conveying a lubricant toeach of the respective ends of said spindle, one of said pipes being ofless length than the other of said pipes, a lubricating cup for each ofsaid pipes, a restricted nozzle on the end of each of said pipes and arecess formed in the surface of the spindle at the end of each pipe. 7

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
